Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative board, and particularly to a method for manufacturing a decorative board using a radiated HB resin as a coating agent.
In this method, patterns such as letters and figures are drawn on the surface of a radiation-transparent plate-like material such as a glass plate using a radiation-curable resin, and then the radiation-transparent plate-like material is breathed on top of the pattern. The radiation cured resin is cured by irradiation.

Glass mosaics, stained glass, and the like are examples of decorative plates in which patterns are drawn on radiation-transparent plates such as glass plates and transparent synthetic resin plates. This chestnut decorative board was manufactured by, for example, drawing a desired pattern on a glass board or a synthetic resin board with chemical paint and then drying and curing it. Due to its poor adhesion to plastic and synthetic resin boards, the paint was repelled during painting, resulting in uneven coating thickness and creating shading in the pattern. In addition, conventional chemical compositions require a long time to dry and harden, resulting in poor work efficiency.Also, they do not have sufficient adhesion to glass plates or synthetic resin plates, so they tend to peel off easily, and do not deteriorate or fade over time. Because it is thin, it has the disadvantage of losing its aesthetic appearance in a short period of time. Furthermore, this very conventional chemical paint is cured by evaporation of the solvent in the paint, so it has the disadvantage of causing many fine cracks due to drying shrinkage that accompanies curing. In this way, moisture infiltrates and accumulates in the minute cracks that occur on the painted surface due to the capillary action, and the moisture that accumulates in the cracks is difficult to evaporate. The deterioration and discoloration are further accelerated by the accumulated moisture, and the cracks gradually spread, eventually causing the paint to peel off from the glass surface, resulting in a significant loss of aesthetics. In addition, when this stile decorative board is used as stained glass by fitting it into a window frame, etc., it deteriorates and fades due to direct sunlight and condensation, and cracks occur due to expansion and storage due to temperature changes.
The problem was that it would peel off from the glass surface.

Therefore, the present invention has been made for the purpose of providing a novel method for manufacturing a decorative board which eliminates the drawbacks of the conventional ones, and which provides a method for manufacturing a radiation-transparent plate-like body such as a glass plate or an acrylic resin plate. Then, patterns such as letters and figures are drawn using radiation-cured resins such as ultraviolet (UV)-cured resins and electron beam (IB)-cured resins that have secret and excellent properties such as continuous hardening and adhesive properties. A radiation-transparent plate-like body is placed thereon, and radiation is irradiated to cure the radiation-curable resin sandwiched between the two plate-like bodies. Hereinafter, referring to the drawings, in Embodiment 11i7 of the present invention, reference numeral 1 is a transparent glass plate, and the upper surface thereof is acrylic-based epoxy thread colored in a desired color by adding pigments of various colors. ultraviolet k such as
Fii! ! The compound resin 2a/%/2h is divided and painted as shown in the figure to form a desired pattern. On the top surface of the glass plate l with the desired pattern drawn in this way,
This glass plate 1 and a transparent glass plate 3 of the same size are put together (see Figure 2). In that case, the glass plate 3 is
If you lower the resin 2 a N2 h vertically from directly above the glass plate 1 and place it on the glass plate 1, the wind pressure to remove insects may cause each resin 2 a N2 h to flow and the pattern to emerge. Slowly rotate plate 3 from the upper part so that the air in the chest of both glass plates 1 and 3 escapes to the side (
(See the dotted arrow) and gently fold the melons together. Excluding each yuzu fat 2
When air remains between the upper surface of a y 2 h and the upper surface of the glass plate 3, the residual air becomes a pool of air and causes each resin 2 a -
%72h, so both glass plates 1 and 3
Allow the dark air to completely escape.

After the glass plates 1.3 are stacked together in this manner, each resin 2a is cured by uniformly irradiating ultraviolet light from above with an ultraviolet lamp 4 (see FIG. 3). At this time, if non-solvent type resins are used as each of the resins 2a to 2h, there are no volatile components, and curing can be performed more reliably. When each resin 2 aw 2 h is cured,
Both glass plates 1 and 3 are firmly integrated by the contacting action of each resin 2 a w 2 h, and the decorative plate A is completed (
Figure 4 Condition) 0 In the above process, each resin 2 a /% / 2 h is cured quickly by ultraviolet rays (1, (by the rule), so it is very easy to work with. If you irradiate from
can be cured. Also, resin 2 a N2 h
is a material that hardens by producing a main reaction, a condensation reaction, and a crosslinking reaction force, and has the characteristic that almost no cracks occur during curing, and also has extremely good adhesion to the glass plates 1 and 3. There is no possibility that the glass plate 1.3 and the resins 2a to 2h will be separated later. In addition, each of the resins 2a to 2h was applied to both lath plates 1.
3, so each resin 2 a w
The thickness of 2h is completely uniform, so there is no shading in the pattern, and the same brightness of the pattern can be seen from both the bow and the back. 1.3, so it will not be damaged or peeled off by external stimuli. In addition, each resin 2a/%/2h maintains complete airtightness, so each resin 2a/%/2h will not deteriorate or fade due to exposure to air, and will not be exposed to wind or rain. Also protected from. Of course, it is not necessary to completely eliminate these residual air bubbles i, and since most of the resins 21 to 2h are protected by the upper and lower plates 1 and 3, it is also possible to use these residual air bubbles as part of the pattern. It is′. In addition, each resin 2 &
~2h has some elasticity even after curing, so even if an external impact is applied to the glass plates 1 and 3, fine brush strokes are absorbed by the elasticity. Therefore, the glass plate 1.3 also has the advantage of being difficult to break. In addition, by changing the amount of pigment added and the thickness of each resin 2a to 211, the color density can be changed to the desired appearance.In this case, as a thickness adjustment means, the periphery between the glass plates 1. , a spacer with a desired thickness may be interposed.

The characteristics of the ultraviolet curable resin 2 & /%/ 2 h described above are also possessed by radiation curable resins such as electron beam curable resins. In addition to pigments, dyes may be used as the coloring agent, but dyes have the disadvantage that they fade more easily than pigments.

FIG. 5 shows another embodiment of the present invention, in which the lower surface of the upper glass plate 5 comprising the decorative plate n'fi is provided with a chevron-shaped top strip as unevenness along its length. A large number of grooves 6 are formed. If the narrow grooves 6 are formed on the lower surface of the glass plate 5 in this way, the incident light will be diffusely reflected and the front side (glass plate 1
Brightness when viewed from the side) and the back side (glass plate 54M)
Special visual effects can be mentioned, such as a different degree of gluing when viewed from above, and a prismatic effect. Furthermore, when the glass plates 5 are brought together, the air between the two glass plates 1 and 5 flows quietly and quickly without creating turbulence along each of the narrow grooves 6 that extend to the end surfaces of the glass plates 5. (see point a in Figure 6), the air venting effect can also prevent the formation of air bubbles. Also, when stacking the glass plates 5, excess resin 2a to 2h applied on the glass plate l
can flow out of the glass plates 1, 5 along each thin groove 6, and due to the partitioning effect, each resin 2a to 2h
Since unnecessary flow of the uncured resins 2a to 2a can be suppressed,
Furthermore, the narrow grooves 6 as irregularities that can prevent the 2h from being mixed with each other may also be formed on the upper surface of the glass plate l.

FIG. 7 shows another embodiment of the present invention, in which 7 is a disc-shaped plate made of transparent or transparent synthetic resin, and a narrow groove 8 is formed on the upper surface of the plate. It is formed radially around the center of 7, and all of the narrow grooves 8 are in communication.
And its tip extends to the end surface of the plate-like body. Narrow groove 8
The radial pattern is symmetrical with respect to any roughness that passes through its center, so no matter which direction the plate-shaped body 7 is rotated as described above and rolled onto the plate-shaped body on which the resin is spread, You can get the same air venting effect. Note that the shape of the narrow grooves 8 is much smaller than the sound intensity of the narrow grooves 6 of the above-mentioned power lath board 5, so it does not particularly improve the visual effect as described above. , and the effect of air venting, resin outflow, and prevention of muddy work cannot be expected to be that great.

FIG. 8(-) shows still another embodiment of the present invention, in which numeral 10 is a glass plate, and a large number of air vent grooves 11 are formed on the surface of the glass plate. The surface shape of each narrow groove 11 is arc-shaped, and each axis is tapered downward from the center ltMN,A of the glass plate 10 toward both end surfaces of the glass plate 10 ( Figure 8(b) & photo).

If the narrow unevenness is formed in this way, when the glass plate 10 is stacked on a glass plate coated with radiation-cured resin, air will flow to both end surfaces of the glass plate 100 as shown by the dotted arrows. It can flow smoothly.

FIGS. 9(&) and 9(b) show still another embodiment of the present invention, in which 1g is a glass plate, and a narrow groove 13 for air venting is formed on the surface of the glass plate. The cross-sectional shape of each narrow groove 12 is an arcuate shape, and the shape is tapered to widen toward one end of the glass plate 12. By forming the narrow grooves 13 as irregularities in this way, the water flows smoothly toward the end surface of the glass plate 12, as shown by the dotted arrows.

As described above, by devising the shape of the air venting unevenness formed on a plate-like body such as a glass plate, the air venting effect can be improved by -bx.

Note that, as is clear from the above first embodiment, it is not necessary to form irregularities on the plate-shaped body. Furthermore, when forming unevenness on a plate-shaped body, the shape and distribution density are not limited to those of the above embodiments, and various design changes are possible.The key is to achieve the desired air venting effect and It is sufficient if a visual effect etc. can be obtained.
．． They do not necessarily need to extend to the end face of the plate-like body 5.7 as in 11, nor do they necessarily need to communicate with each other as in the narrow grooves 8 mentioned above. = The method according to the present invention can also be applied to existing window glass. That is, in FIG. 10, 15 is window frame 1
A desired pattern is drawn on the surface of the window glass with radiation curing resin 17, a glass plate 18 is placed on top of the glass plate 18, and the resin 17 is irradiated with radiation using a portable radiation irradiator 19. Just let it harden. Of course, the above work may be performed by removing the window frame 16 from the window holder 20 and placing it on the floor.

As explained above, in the method according to the present invention, a radiation-curable resin 2 a w 2 h is applied to the surface of a radiation-transparent plate-like body l.
A pattern is drawn with the 1M radiation hardening resin 2! L/
